Your Lord is God who established His dominion over the Throne (of the realm) after having created the heavens and the earth in six days. He made the night darken the day which it pursues at a (considerable) speed and He made the sun and the moon submissive to His command. Is it not He Who creates and governs all things? Blessed is God, the Cherisher of the Universe. 54 Call on your Lord humbly and secretly; surely He does not love those who exceed the limits. 55 And do not make mischief in the earth after it has been set in order, and call upon Him with fear and longing. Surely Allah's mercy is close to those who do good. 56 It is God who sends forth the winds as harbingers of His mercy, and when they have gathered up the heavy clouds, We drive them on to a dead land where We cause rain to fall, bringing out all kinds of fruit, just as We will raise the dead to life. Perhaps you will take heed. 57 As for the good land, its vegetation cometh forth by permission of its Lord; while as for that which is bad, only the useless cometh forth (from it). Thus do We recount the tokens for people who give thanks. 58

Notes and Instructions
كيف تعمل منظومة تمارين الحفظ؟ عند أدنى مستوى 0، تكون كل الكلمات ظاهرة. بينما يُخفي أعلى مستوى 9 كل الكلمات. فكيف تعمل المستويات المتوسطة، مثل 3، على سبيل المثال؟ قد تعتقد بأن المنظومة تخفي 3 من كل تسع كلمات بدقة. ليس تماما! في المستوى 3، لكل كلمة فرصة اختفاء بنسبة 3 من 9، و6 من 9 لتكون ظاهرة. بمعنى آخر، من الممكن، ولكن باحتمال شبة معدوم، أن تكون جميع كلمات المستوى 3 مخفية، أو أن تكون جميعها ظاهرة! وكذلك أيضًا، ففي المستويات المتوسطة، وبما يتناسب مع مستوى الصعوبة، يمكن أن تكون المخابئ غير كاملة أو شفافة جزئيًا بحيث تظهر الكلمات جزئيًا تحتها.
How does the memorization exercise algorithm work? At the lowest level 0, all words are visible. While the highest level 9 hides all words. What about at mid-level, like 3, for example? You might think that the algorithm hides precisely 3 out of every nine words. Not quite! At level 3, each word has a 3 out of 9 chance to hide, and 6 out of 9 to be visible. In other words, it is possible, but highly unlikely, for all words at level 3 to be hidden, or, that all of them to be visible! Also, at mid-levels, and in proportion to the difficulty level, hideouts can be partially incomplete or transparent so that words may be partially visible underneath.
